Last week I treated myself to a new phone - a Nokia E72 to replace my ageing Nokia N95.

I use my phone for quite a bit of stuff, including push email for both work and personal, as well as lots of Twittering and VoIP over WiFi.

Over the last couple of months the battery on my N95 has been worsening, and while I was once able to do all of the above and still have some battery to spare at the end of a long day, I was finding my phone was flat by about 10pm, or sometimes earlier if I was using it more heavily than normal.

One of the reasons for going for the E72 was its 1500mAh battery, 50% more capacity than the 950mAh battery in the N95. Based on this I was thinking I might even be able to get close to 2 days out of the battery.

I however am finding that the battery, despite being brand new and of much greater capacity, is actually giving me about the same, or slightly less life than my aging N95 battery was able to manage.

Has anyone else found this with the E72?

I am wondering if maybe there is something in the Firmware that is causing the phone to chew through battery excessively.
